Expert Answer:

Intensity can be understood as energy provided per second i.e Power (emergy per second).
Thus we can say that intensity is proprotional to energy E, which, for a photon is given by:
begin mathsize 12px style straight E equals hf space equals space hc over straight lambda end style
Where 'h' = 6.626 x 10-34 Js is a universal constant called Planck's constant,
'c' is the speed of light in vacuum and
'λ' is the photon's wavelength.
 
Thus, intensity and frequency of a photon in an electromagnetic wave are directly propotional to each other,
